i have a set 290 cc injectors, can i set this in my 91 accord lx and will i have to program my ecu to get more fuel

 

Also ther are no real gains, 290cc aren't much more than what's in there stock anyway. Larger injectors alone will do next to nothing for you. You have approx. 240cc stock 50cc is worthless.

 

while what can i do in the meantime to get some power i have a voltage stabilizer to put on i plan on the h22 swap. do you guys have any suggestions

 

The only mods you can make while waiting for the swap are intake, exhaust, voltage stabilizer, (universal items or items that will fit afterwards) otherwise you'll have to take it off once you do the swap ie. a header.
